No idea how to refactor this into Code Igniter

In earlier versions, CI supported a libraryname_init.php file stored under init/ and the feature was removed some time ago. The library itself was stored under application/libraries. Adding certain libraries such as ADODB was less of a problem back then.

You might take a look at the approach used by DanFreak to integrate SwiftMail with CI.

I believe that Daniel successfully used similar approaches to integrate other libraries.
